Title: Sheet metal excellent in laser weldability
Inventor: ARAI SHINICHI
IPC: B23K26/21
Filed: 1986-02-20
Abstract: PURPOSE:To prevent the occurrence of welding defects such as burn through, defective deposition, etc., in laser welding of sheet metal for cans, etc., by specifying respective values of center line average height Ra and the number PPI of peaks of a roughness curve to the basic length. CONSTITUTION:In the sheet metal for cans, etc., the surface roughness is regulated so that number of roughness-curve peaks with a height of >=0.3mum from the center line of the roughness curve per inch of basic length is 80-300 by PPI. Further, the center line average height Ra by JISB0601 is controlled to 0.15-1.0mum. This surface roughness is provided by means of transfer method by use of rolls for rolling, etc. The sheet metal having the above surface roughness shows excellent high-speed weldability in butt laser welding, so that a weld zone excellent in tensile fracture strength can be obtained.

Title: Microhardness measuring instrument
Inventor: YANAGISAWA MASAHIRO
IPC: G01N3/42
Filed: 1985-02-22
Abstract: PURPOSE:To detect the microhardness of a thin film with high precision by pressing an indenter against a sample from above and operating a press-in driver and a position displacement gauge for the indenter associatively with each other. CONSTITUTION:The sample 1 is placed on the pan 3 of a scale 2. Then, the sample 1 is pressed in by a piezoelectric actuator 5 which has the indenter made of diamond in a triangular pyramid shape. The displacement gauge 7 is fitted to the indenter 4. This displacement gauge 7 detects displacement by irradiating a mirror 6 with light 8 and receiving its reflected light. Further, the piezoelectric actuator 5 and displacement gauge 7 are operated associatively with each other. Thus, the press-in driver and position displacement gauge are associated operatively with each other, so the hardness is detected with high precision.

Abstract: PURPOSE:To produce extremely pure water having high purity by subjecting the org. material in water to be treated to oxidation decomposition by the irradiation of light in the presence of a photocatalyst formed by depositing group VIII metal of periodic table and/or the oxide thereof on a fine particulate inorg. semiconductor. CONSTITUTION:The photocatalyst is prepd. by depositing about 0.1-15wt% group VIII metal (e.g., Pt) and/or the oxide thereof (e.g., RuO2) on the fine particulate inorg. semiconductor (e.g., TiO2, CdS). The org. material contained in the water to be treated is subjected to the oxidation decomposition by the irradiation of the light (e.g., irradiation of the light by 500W high pressure mercury lamp) in the presence of such photocatalyst. Such treatment stages is combined with a known technique for producing the ultrapure water, by which the extremely pure water having high purity is produced more efficiently than by the conventional technique.

IPC: H04B1/40
Filed: 1994-03-03
Abstract: PURPOSE:To completely mute a data signal transmitted before a voice signal. CONSTITUTION:When a carrier C is detected as shown in figure (1), a noise squelch signal N2 is generated as shown in figure (4) with a delay for a time W14 longer than a bit synchronizing signal D5 and a frame synchronizing signal D6 of a data signal D8 shown in figure (6). On the other hand, a data signal D7 of the data signal D8 is identified and whether or not the signal corresponds to a concerned station is discriminated and when the signal corresponds to the concerned station, the reception of the signal D7 is finished and an identification signal ID is switched from a high level to a low level as shown in figure (7). The sound processing of the data signal D8 is surely blocked by releasing muting only for a period when a noise squelch signal N2 is at a high level and the identification signal ID is at a low level as shown in figure (8) and only the voice signal addressed to the concerned station is processed into a sound signal.

Filed: 1991-03-01
Abstract: PURPOSE:To prevent a circuit element from being deteriorated or destroyed due to electrostatic discharge by connecting the input circuit of a built-in power source switching circuit block to circuit ground via a low resistor when a device is used as a simplex one. CONSTITUTION:When the supply of an external power source is cut off by extracting a memory device from a system main body, etc., a power source IC 14 equivalent to the power source switching block detects the voltage drop of a primary side power source 7. Thereby, the connection of the primary side power source 7 and a secondary side power source 8 can be disconnected. Therefore, the secondary side power source 8 is switched to a backup power source by a built-in battery 20. Since the voltage of the primary side power source 7 goes to around the circuit ground, a control circuit block 21 outputs a signal which turns on a low-impedance making circuit 22. A low-impedance making circuit block 22 is turned on, which connects the primary side power source 7 to which the input circuit of the power source IC 14 is connected to the circuit ground 9 with a sufficiently small resistance value.

Abstract: PURPOSE:To offer an electric signal level controlling circuit whose number of degrees of freedom is large, by providing a changeover switch on the electric signal level controlling circuit, executing charge and discharge, and varying the impedance of an electric element. CONSTITUTION:When an electric signal of a voice is applied to an input terminal T10 from an output part of an apparatus and a common terminal of a changeover switch SW1 is switched from a fixed contact 2 to 1, positive DC voltage accumulate positive charge in a capacitor C1 of a charging and discharging circuit, and a collector current of a transmsistor TR5 flows.

When the switch SW1 is set to the contact 2, a transistor TR1 conducts, therefore, a signal inputted from the input terminal T10 is not outputted from the output terminal T20, and when said switch is set to the contact 1, the transistor TR1 is triggered to a nonconducting state, and the electric signal is capable of advancing to the output terminal T20.
